Cancellation of liability policies; plan for apportionment of certain applicants.

No motor vehicle liability policy which is obtained to effect the return of any driver license or registration shall be canceled by an insurer issuing the same unless 10 days’ notice of such cancellation shall be given to the department on a form prescribed by it and to the insured, except that when evidence has been furnished of the holding of a motor vehicle liability policy, and subsequently evidence is furnished of the holding of such a policy subsequently procured, the later policy shall, on the date evidence is furnished, terminate the policy as to which evidence was previously furnished with respect to any vehicle designated in both policies.
